Intracellular recordings were made on cells of Corti organ from low-frequency region (third turn) of guinea pig cochlea, the recording sites being confirmed by HRP injection and subsequent histology. Response characteristies of the hair cells were studied. The Inner hair cells (IHCs) possessed relatively low resting membrane potentials in contrast to higher ones of OHCs. The receptor potentials from both cell types, in response to tone bursts, consisted of a combination of AC and DC components. For the low-frequency region, the receptor potentials were dominated by AC component. The causes of recording failure were discussed.
在豚鼠耳蜗低频区（第三圈）的柯蒂氏器细胞上进行细胞内记录，记录位点通过辣根过氧化物酶注射及后续组织学检查得以确认。研究了毛细胞的反应特性。与外毛细胞较高的静息膜电位相比，内毛细胞的静息膜电位相对较低。两种细胞类型对短纯音的感受器电位均由交流（AC）和直流（DC）成分组成。对于低频区，感受器电位以交流成分为主。讨论了记录失败的原因。
